1 Claim.

This invention relates to a bag which is particularly adapted for use by persons who customarily carry their lunches in paper bags but may be used as a general utility bag and any articles desired may be placed in it.

At the present time many persons carry their lunches to work or school in paper bags which become soiled or torn and therefore discarded after being used once. Therefore one object of the invention is to provide a bag formed of waterproofed fabric such as Zelan-treated poplin which may be folded into a small compact mass after lunch has been removed from it and taken home in a hand bag or pocket for washing, if necessary, and reused.

Another object of the invention is to provide a bag so formed that when opened its upper end will be unobstructed and of such dimensions that contents of the bag may be easily removed and the bag then folded.

Another object of the invention is to provide a bag formed from a fiat blank of material which has edge portions sewed together to form a bag having a bottom and side walls, upper edge portions of the walls carrying grommets or eyelets through which a draw string is passed for constricting the mouth of the bag after lunch or other articles have been placed in the bag.

Another object of the'invention is to provide a bag having a closure cap which may also be formed of waterproofed fabric or of thin leather and is provided with tabs for detachably holding it in position for closing the constricted mouth of the bag.

Another object of the invention is to provide a bag which is of simple construction and capable of being manufactured at small cost.

The invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a side elevation of the improved bag showing the same closed.

Fig. 2 is a top plan view of the closed bag.

Fig. 3 is a vertical sectional view taken along the line 3-3 of Figure 1.

Fig. 4 is a fragmentary sectional view taken vertically through the upper end of the bag at right angles of Figure 3.

Fig. 5 is a perspective View of the cap for closing the upper end of the bag.

Fig. 6 is a perspective view showing the bag opened.

Fig. '7 is a fragmentary sectional View taken along the line l-'l of Figure 6.

Fig. 8 is a fragmentary sectional view taken along line 88 of Figure 6.

Fig. 9 is a View of the blank from which the bag is formed.

This bag is formed from a blank of water proofed fabric, such as Zelan-treated poplin or other suitable material, and referring to Figure 9 it will be seen that the blank I has end portions 2 which are of rectangular outline and connected by a strip 3 which extends between their inner ends and is of approximately one-half the width of the end portions and spaced equal distances from opposite side edges thereof. Notches 4 are formed adjacent corners of the end portions so that a seamstress may readily fold end portions "of the blank along margins thereof after the end portions have been folded along the dotted lines 5 and side edge portions of the two end portions 2 sewed to each other to form seams 6 and inner edge portions of the end portions of the blank have been sewed to side edge portions of the tongue 3. The blank will thus be formed into a bag I which is of even dimensions throughout its depth and has a bottom 9 formed by the tongue or strip 3 of the blank and side walls [0 and end walls H, the side walls being integral with the bottom and the end walls being secured to the bottom by seams l2. Upper edge portions of the walls are folded along inner ends of the notches 4 at outer ends of the blank and sewed to form a hem l3 about the open upper end of the bag. Near their upper ends the side walls ID are formed With openings M which may be reinforced by buttonhole stitching or eyelets and through these openings are passed portions of a draw string or tape I5 which serves as a sheering cord and has portions l5 projecting from the end walls H of the bag and constitute loops or handles by means of which the bag may be easily carried. By grasping the handles and exerting pressure against the end walls H the upper portion of the bag may be constricted to the partially closed condition shown in Figures 1, 2, and 3. The bag should be fully closed when filled with lunch and in order to do so there has been provided a cap l6 which may be formed of leather or waterproofed fabric and at opposite sides carries tabs ll formed with buttonholes ill to receive buttons l9 sewed to opposite side walls of the bag near the open upper end of the 'bag. When one of the buttons is released the cap may be swung upwardly and turned about the other button and suspended therefrom at a side of the bag, the mouth of the has" being then spread to the fully opened position so that lunch may be removed from the bag. The bag may then be folded into a compact mass andplaced in a pocket or hand bag and taken home for reuse. When the bag becomes soiled it may be easily washed and dried and it will be restored to its original clean and attractive condition. The cap is detached from the bag during washing so that the leather from which it is formed will not be spoiled by immersion in water.

Having thus described the invention, what is claimed is: 4

A lunch bag comprising a body formed from a single piece of water-proofed fabric, said body having a bottom and side walls and end walls and formed from a blank having rectangular end portions connected by a strip extending between their inner ends midway the width thereof, the blank being folded across ends of the said s'tr'i-pto form a bottom for the bag of the strip and the rec tangular end portions having their side portions projecting from sides of the strip brought towards each other and sewed along the meeting margins to each other to form side walls integral: with. the bottom and end walls having vertical seain's midway their width, lower ends of the end walls- 'being seamed to the bottom, u per edge portions'of the walls being folded and sewed "to form a hemmed upper'edge for the bag-, -there being open- 4 ings formed through the side walls adjacent their upper ends in transverse spaced relation to each other, and a sheering cord threaded through the openings and the hemmed upper edges of its side walls with looped portions projecting from end walls of the bag and constituting handles for the bag, the side walls being constrictable along side portions of the sheering cord to constrict the upper portion of the bag and close the bag.
